"I purchased the Leela Dog collar about two and a half weeks ago. The next day after I received it, I drove 18 hours (round trip) in two days to pick up a new puppy. As soon as I set the puppy in my car, she was barking hysterically. I put the dog collar on her, and within about three seconds her entire energy changed. She got silent and calm, yet alert and intuitive… The first night in my house, she howled like a wolf! She already has learned two tricks, hardly barks, and responds to me like she understands everything I'm speaking. Her bark sounds are bold and deep for a puppy, and her energy/energy levels/intuitive side are truly advancing every day. I'm really looking forward to seeing this continue!"
